Cloudflare Introduces Speed Brain to Instantly Make Web Pages 45% Faster

One of the rules to ensure it works:

> The page requested by the prefetch does not invoke a Worker.

I guess this restriction kind of makes sense for this?

Funny enough though, some of the best speed optimization Cloudflare stuff only works with Workers if you use a Fetch (aka, you must have an origin!).

The Worker Cache API for example doesn't support Polish/Mirage or many other Cloudflare features.
